Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

The HC-SR04 ultrasonic range sensor is a pretty cool pre-wired module that you actually enjoy using when you start playing with electronics, microcontrollers, and robotics. As you might have noticed, ...

A new technology has been developed that enables cuffless noninvasive blood pressure monitoring by using ultrasonic to track ...

Infineon Technologies AG has claimed the first integrated one-chip solution for a MEMS-based ultrasonic transducer in a smaller footprint with improved performance and higher functionality. The MEMS ...

We know what you’re thinking: with so many wireless modules available for just pennies, trying to create a physical data link using ultrasonic transducers like [Damian Bonicatto] did for a short-range ...

Today, a vast number of micro-manufactured sensors, actuators and components vibrate at frequencies in the high MHz range. Some examples of these high-frequency vibrating systems include surface ...

Imagine if you could slide your finger up and down the side of your AirPods to control the volume. Or if a few taps on the aluminum shell of your toaster could set the perfect time and temperature for ...
